Subject: Is it possible to run a linux on multiple clusters if CCI is missing

Hi all,
Say that if one SoC has 4 clusters, and each cluster has an A78. Every A78 has its own SCU to maintain cache coherence,
but this SoC doesn't have CCI, so there is no hardware to maintain cache coherence between the 4 clusters.
My question: is it possible to run a single Linux kernel on 4 clusters?
If so, how to do it and how can the cluster cache coherence be maintained?
Regards,
Li
